Craig, you impress me with your courage to dive into these things. I too, am very glad we have many people available on the net who have experience and are so willing to share it. I have never been mechanically inclined so I tend to do a lot of reading just because I find it interesting and I like understanding better what makes the motor run or not run....LOL. Unfortunately, usually when I try to follow instructions from others, I wind up screwing something up and the repair bills are FAR higher than they would have been than if I just would have taken it to a qualified mechanic in the first place. I think there are so many little steps in many procedures that if not followed exactly, disaster is right around the corner. The guys who do these things on a regular basis generally don't miss those things, but if they are left out inadvertently while passing on information to others less skilled, the problems only get bigger. In my opinion Craig, you have either had some very bad luck or you are just hexed, as your problems seem never ending.
